Method of linking devices to gaming machines

ABSTRACT

Gaming software interfaces to hardware through high level drivers loaded in resource repositories. The high level drivers can be software or hardware drivers. Software drivers can simulate hardware, connect to other parts of the gaming software, or combine functions by calling other software and hardware drives. New drivers can be added easily, allowing gaming software to use new hardware with little or no changes.

The present invention is a method to link Input/Output (“I/O”) devicessuch as gaming machine peripheral devices to gaming machines in such amanner that the gaming machine can determine, among other things, thenumber and types of devices connected, the prior use of the devices andways of upgrading the devices without interfering with the operation ofthe gaming machine.

BACKGROUND OF THE INVENTION

Historically, gaming machines have always been monolithic. That is, theyhave a single central processing unit (CPU) running a single block ofsoftware and/or firmware that controlled all the hardware directly. Somehardware devices have a micro-controller in them to perform tasks for anexplicit hardware function, but the game CPU to hardware interface isstill monolithic in nature. An example of two smart devices that arecontrolled by the single game CPU are the following: U.S. Pat. No.5,190,495 to Taxon and assigned to Bally Manufacturing Corp. for a highcapacity coin hopper for a gaming machine, which uses traditionalcontrol lines as if it were a non-intelligent hopper. U.S. Pat. No.5,420,406 to Izawa et al, and assigned to Japan Cash Machine Co., Ltd.,which discloses a bill acceptor that requires a micro-controller toperform the operation of validating currency, but is interfaced via adedicated serial port. The software to talk to these hardware deviceswould, generally, always be included in the software block that runs onthe game CPU, whether or not that device was connected to the game. Thisstatic approach affects the CPU layout, since the input/output (I/O) isincluded on the CPU board, and it affects the design of the softwarethat runs on the CPU. The resulting method of integrating the softwareto the hardware on a monolithic CPU makes the software monolithic,harder to add new interfaces to hardware and harder to maintain existingcode. By adding an extra level of intelligence to the hardware devicesto allow them to be abstracted, such as in NuGame's U.S. PatentApplication 0015 1 973 992 4643, for an I/O Interface and DeviceAbstraction, filed 24 Jul., 1998, the software (which runs on the gameCPU) can be modified to allow for dynamic hardware connections. Thisextra level of intelligence permits the developer to write interfacingsoftware modules that are both smaller and easier to debug and maintain.In addition, properly abstracted hardware can be hot-swapped since thesoftware will automatically load the right driver and make theconnection to the new hardware.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to the Figures, wherein like numerals reflect likeelements, a method to dynamically link abstracted devices (i.e.,hardware) used in, by, or for, gaming machines such as a slot machine togaming software is disclosed.

The method, in its preferred embodiment contains a resource managercomprising six functional blocks, namely:

(1) a Resource Manager Control Task 20;

(2) an I/O Communication Driver 30;

(3) a Low Level Driver Manager 40;

(4) a High Level Driver Manager 50;

(5) Driver Pools 60 and 70 and

(6) Resource Repositories 80, 90, 100.

Referring to FIG. 1, the Resource Manager Control Task 20 is the commandand control interface for the Game System. It also controls the updateand configuration of the drivers and resource manager itself. The I/OCommunication Driver 30 is the task that actually initiates andmaintains the communication link to the Input/Output Control Board(IOCB) 120.

A detailed description of the IOCB is found in NuGame's patentapplication Ser. No. 60/085,892 for an Intelligent Input/Output ControlSystem, filed 18 May, 1998. The Low Level Driver Manager 40 loadsdrivers, 42-48, that are allowed in the configured jurisdiction, for thehardware that the IOCB reports as being available. The High Level Drivermanager 50 loads two different types of drivers:

(1) High Level Device Drivers 52, 54, 56, 58 as shown in FIG. 1; and

(2) High Level Software Drivers 62, 64, 66, 68.

High Level Device Drivers connect to their Low Level Device Drivercounterpart as shown in FIG. 1. There can be many High Level DeviceDrivers connected to one Low Level Driver. Each of the Device DriverManagers has a Jurisdiction Error table built into it. This table willtell the Driver Manager 50 whether to ignore, warn about, tilt lockupallowing operator override or fatal tilt on columns of different erroroccurrences. There are also Driver Pools 70 and 60 associated with eachDriver Manager 40 and 50 respectively. These contain the drivers thatare available to each of the Driver Managers. The Driver Pools 70 and60, using a relational index and table based on jurisdiction, and devicetype, allow the Driver Managers to find the proper driver to load. Asecond index for each driver based on revision levels will tell if thedriver revision level can work with the hardware revision level. TheHigh Level Drivers are loaded from Repositories 80, 90 and 100.

Repositories such as Repository 1 80 in FIG. 1 are groups of High LevelDrivers, both software and hardware, that are of the same category andare controlled by system level tasks such as 82. The RepositoryControlling Task 82, 92, 102 is the interface between the system and thehardware drivers of the resource manager. There are three types ofRepositories: (1) Prioritized, (2) General, and (3) Unknown. Eachprioritized Repository deals with one type of object and they can thusbe organized into a preferred utilization order. (Gaming softwareexamples of Prioritized Repositories would be: “Bet”, “Pay” and“Collect”.)

General Repositories are groups of drivers that could apply to manydifferent unrelated types of object, but are kept in a localized groupto allow easy access. (“Game Interface” would be an example of a GeneralRepository.)

Although not shown in the Figures, Repository, some examples of driversin the “Game Interface” would be: buttons, reel motor controller, bonustoken hoppers, meters, progressive, display, tower, bell and secondarygame features. Unknown Repositories are Repositories requested to becreated by Repository Controlling Tasks that are not in the High LevelDriver Manager's table of Jurisdiction and Repositories. In the UnknownRepository case, The Repository Controlling Task, of the state machine,must request all operations on it explicitly.

Other types of devices that may be connected to the gaming machineinclude (but are not to be limited to), hoppers, printers, coinacceptors, diverters, reel stopper devices, bill acceptors, cardreaders, credit or debit or smart card readers, progressive displays,buttons, lamps, button lamps, bells, jackpot bells, lights, key switchesor other devices known to those skilled in the art.

On power up, the game software starts the Resource Manager Control Task.The game software waits for the Resource Manager to send the location ofthe game's non-volatile (referred to as “NV”) storage. If an erroroccurs, then there is a problem in either communicating with the IOCB,or the configuration of the IOCB. After the Resource Manager ControlTask has initialized, the I/O communication driver attempts to find theprimary IOCB. If the IOCB is plugged into the Industry StandardArchitecture (ISA) bus then the I/O communication drivers would querystarting at 0C00 hex 302 skipping every 16 bytes up to 0D00 hex 304until the IOCB is found at 340. In the preferred embodiment, the gamingmachine used with the present invention includes a CPU manufactured byIntel Corp. as specified in NuGame's Patent Application Ser. No.60/094,068 for an I/O Interface and Device Abstraction, filed 24 Jul.,1998.

In the arrangement of the IOCB on the ISA bus, there are two registersin the I/O memory address space. The first register is a message portfor data packets to go back and forth between the CPU and IOCB 120. Thesecond register is an I/O port status register. This register tells theCPU if there are any message data bytes to be read, if the IOCB is readyto receive any message data bytes and whether the last message data bytehas been read. At any time that the IOCB 120 makes a change to thestatus register, the IOCB 120 will also trigger an Interrupt Request(“IRQ”) line on the ISA bus. The IOCB 120 can be configured to use anyavailable IRQ lines, but will generally use IRQs 7, 8 or 11. Anysecondary of tertiary IOCB in the game must use the same IRQ as theprimary IOCB; otherwise an error will be generated.

The I/O communication driver 30 will load au Interrupt Service Routine(“ISR”) at IRQs 7, 8 and 11. Starting at base I/O address 0C00 hex, theI/O driver reads a byte at I/O address base plus one, to see if it couldbe the IOCB status register. If the byte read is the status register,the bits will be a unique Pattern 314 as specified in NuGame's PatentApplication Ser. No. 60/094,068, filed 24 Jul., 1998 for an I/OInterface and Abstraction.

If there is no port at the address at all, the bus read returns FF hex.Only if the byte read is likely to be the status register will the I/Odriver then try to read a message from IOCB message port at base I/Oaddress, 0C00 hex. If the IOCB is there at 312, the status register isupdated and an interrupt is triggered via the IOCB configured IRQ lineat 314. If more than one IRQ based ISR detects an interrupt for thechange, the I/O communication driver will issue a fatal tilt message at316, 318 stating there are multiple IOCB IRQs. If no ISR detects aninterrupt at 314, the I/O communication driver will skip to the nextaddress at 322. If the status register is okay and one ISR detected thechange, the I/O communication driver will attempt to read the data portfor a message. If the message is not valid, but the status register isoperating properly at 330, changing bits to show another byte ready toread at 332, the I/O driver will continue to read the message port asshown in FIG. 2 until it times out after thirty seconds.

If the message packages have been corrupted in any way because theydon't conform to the I/O Interface Protocol at 336, but the statusregister was working properly, the I/O driver stops scanning and goes tothe next port address to be tried at 322. If the status register readwas not a pattern allowed for the IOCB at 330, the driver will add 16 tothe base address, now 0C10 hex, and try reading base I/O address plusone, 0C11 hex returning to 304, 308, etc., for the status register andso on until 0D00 hex. If the I/O driver has not found the IOCB inscanning the I/O memory address spaces between ranges 0C00 hex and 0D00hex, the I/O communication driver will issue a fatal tilt messagestating no IOCB found. If the message received at 334 was a “linkrequest” message with a correct Cyclic Redundancy Code (“CRC”) andcommand code shown at 336, and if the ISR IRQ detected has always beenthe same one, at 320 the I/O driver will unload the other two ISR at338. If the ISR IRQ has changed at 320 to 318 the I/O driver will issuea fatal tilt stating the IOCB IRQ changed during scan. (See FIG. 2 b).

Once the I/O communications driver 30 establishes a connection to anIOCB, during the scan for the presence of an IOCB, the resource managercontrolling task 20 goes to the next phase. The first IOCB found duringis labeled the primary IOCB. There could be zero, one, or two additionalIOCBs connected to the game CPU. As described in NuGame's patentapplication for an Intelligent Input/Output Control System, Ser. No.60/085,892, filed 18 May, 1998. In the “USB” and “Firewire” protocols,the IOCB's would be daisy chained on the respective media. In the caseof an ISA interface, the IOCB, would each plug directly into the buslike a PC “ISA” card, or a PC-104 card (used in embedded systems to pluginto the ISA bus), or a PC-104+“PCI Bus” card.

Once reliable communications have been established between the I/Ocommunication driver 30 and IOCB 120, the I/O communication driver 30requests the primary configuration data from the primary IOCB. Theprimary configuration data is passed on to the resource manager controltask 20 for evaluation. (See FIG. 3.). This data contains thejurisdiction for this game, the interface type and address of anysecondary IOCBs, and the type and address of the primary, secondary, andtertiary non-volatile storage. The configuration data block has a CRCsignature which is checked to insure the data is valid, as shown frompoints 440 through 450. If the CRC does not match the recorded block CRCfor that device, the primary IOCB's configuration is not valid. Thisresults in a fatal tilt message being issued stating that the primaryIOCB configuration data failed the CRC check. The next thing checked isthe jurisdiction entry at 446. If the resource manager control task 20does not recognize the jurisdiction at 446 and 448, from a table ofknown jurisdictions, a fatal tilt message is issued stating that thejurisdiction configuration data has an invalid jurisdiction.

The resource manager control task 20 then checks the configuration ofadditional IOCBs if present. Since there can be as many as twoadditional IOCBs installed in the game, the configuration block has anaddress field for each of these entries is an I/O address from 0C10 hexto 0D00 hex. A secondary IOCB entry must be addressed beyond the primaryIOCB's 110 address, but not necessarily contiguously. The tertiary IOCBentry must be addressed beyond the secondary IOCB address, which inturn, must be beyond the primary IOCB address. The verification of theaddress of the secondary and tertiary IOCBs is performed as shown inFIG. 3 at 454 through 468. If the entries are not in order (at 456) andbeyond the primary IOCB address, the resource manager control task 20will issue a tilt message at 466 saying that the data for the secondaryIOCB in the configuration data are invalid. This is not a fatal errorand the resource manager control task can proceed to allow the operatoroverride the tilt to continue (not shown). If there are one or twoentries for secondary IOCBs and they are both valid (i.e., in order),then the resource manager control task will start an extra I/Ocommunication driver for each entry at the given address. The newlyinitiated I/O communication drivers for the primary or secondary IOCBwill not automatically scan for the presence of IOCBs. The I/O Commdrivers will use the addresses given in the config block. They will onlycheck for IOCB's at that address.

If the I/O communication driver 30 cannot establish communication withan IOCB at the address passed to it the resource manager control task 70will issue a tilt message stating which secondary IOCB address entriesin the primary configuration data are in error and then allow theoperation to override the tilt to continue. At this point, resourcemanager control task 70 can do no further error checking on the primaryconfiguration data. The remainder of the error check for configurationis under the control of another gaming system task which manages the NV(non-volatile) storage for the game software. The NV storage task is ata higher level from the patent consideration.

FATAL TILT is a catastrophic event that results from broken hardware,corrupted software, illegal hardware or illegal software that requiresmanual correction and/or reinitialization. The casino operator wouldhave to open the game up, or pull it off the floor.

The game must stay in FATAL TILT until corrected by the casino operator.This is a known feature in gaming “art”.

The resource manager control task 20 now sends the section of theconfiguration block that details the NV storage location to the gamingsoftware. The resource manager control task now waits for the NV storagetask to be started up by the game software. After the resource managerused the configuration data to find the game's primary and any redundantNV storage, the game software starts the NV storage task. If the NVstorage task starts without errors, the Resource Manager Control Task 20must now request the NV storage set for the resource manager be attachedto the Resource Manager Control Task 20. This NV storage set has therecords of resource manager settings and lists of the game prior to thegaming machine being powered down (i.e., shut off).

The NV storage set attached to the resource manager 20 containsinformation on the hardware types, their identifications (IDs) andstatus that were connected to the IOCB 120 before the last power down,and the software revision, their identifications, levels of the resourcemanager and device drivers. This information allows the resource managerto inform the system when hardware or software has been changed. Theresource manager control task 20 now starts the Low Level Driver Manager40 after the NV storage set has been attached. The operations of the LowLevel Drive Manager 40 are illustrated in FIG. 4. The NV storage setalso has a CRC signature which is checked to insure the data is valid.The CRC signature for the NV storage is verified by the resource managercontrol task 20 in a manner similar to that shown in FIG. 2 b for theother system hardware. If the CRC value isn't valid, a jurisdictionbased warning message is issued.

As shown in FIG. 4 at 550, the NV storage set is either cleared (i.e.,declared valid) or not cleared, as shown at 550, the Low Level DriverManager 40 then issues an error message which is either a “WARNING,” a“TILT” or “FATAL”. In all cases, where the NV storage set is determinedto be invalid, the resource manager 20 will not be able to inform thegame system that change from previous hardware connected to the systemhas been made. In the case of valid NV storage, the resource manager 20is able to inform the game system of a hardware change since the systemwas last powered off.

The next functional block of the resource manager is the low leveldriver manager 40. The low level driver manager requests the IOCB deviceinformation. This information contains the IOCB's type, revision level,and serial number. This information is compared to what is stored in theNV storage set, and, if it's different from the information previouslystored, a message about the change is sent to the game software log andthe NV storage set is updated with the new IOCB device information. Thelow level device manager then sends a request through the I/Ocommunication driver 30 to the IOCB 120 for the list of attachedhardware devices.

The low level driver manager 40 uses this list to load drivers at 500from the low level driver pool. (See FIG. 4.) Each attached hardwaretype is sent from the IOCB 120 through the I/O communication driver tothe low level driver manager 30. The manager checks the driver poolhardware index and table which is built with the current jurisdiction,known hardware types, plus hardware revision levels. (See FIG. 4 b fordiagram of configuration tables and indexes available). Maintaining alisting of the hardware revision levels in hardware index (FIG. 4) isnecessary because hardware and software changes to fix problems or addfeatures are never uniformly installed in equipment out in the field.

For known hardware at 516, the hardware index will point to one of thefollowing:

-   -   (1) a valid hardware driver in the pool;    -   (2) an entry named “IGNORE”, meaning that the hardware should be        ignored for this jurisdiction, but not error message sent;    -   (3) an entry named “WARNING,” meaning ignore the hardware, but        post a warning message;    -   (4) an entry named “TILT,” meaning send a message, lockup the        game, but allow an operator override; or    -   (5) an entry named “FATAL,” meaning post an error message and        lockup the game. (See FIG. 4, at 534-536).

If any entry for the hardware is not in the hardware index (at 518), orthe revision level does not match any of the drivers, the hardware typeis unknown, and, according to the action table 528 for the jurisdictionerror table at 393-545, built into the low level driver manager, thegame could:

(1) ignore it;

(2) post a “WARNING” message;

(3) post a “TILT” message and lockup with the operator allowed tooverride; or

(4) post a “FATAL” message and lockup the game (FIG. 4, at 534-536).

The hardware processing steps for each hardware item are illustrated inFIG. 4, with FIG. 4 summarizing the information and error messages thatare issued in response to actions taken in FIG. 4. As each entry on thelist of attached hardware device is processed, the low level drivermanager 40 builds a new list at 532 from the attached hardware listcontaining fields for:

-   -   (1) the action taken by the low level driver manager, and if a        driver was loaded;    -   (2) the driver information and the hardware information obtained        from the hardware.

This information will have revision levels of the software and theserial numbers of each hardware item. If at any point in the processingof the list of attached hardware, a “TILT” type message is issued (at522, FIG. 4), it will pend until all the hardware entries have beenprocessed (524). All other types of message actions are executed as theyoccur, thus the “IGNORE” and “WARNING” messages which are not criticalto the operation of the system are issued in real-time. Similarly, a“FATAL” message to lock up the game is sent immediately upon itsoccurrence (536). If at the end of processing the list of attachedhardware there have been no “FATAL” tilts, the low level driver managerposts any pending “TILT” lockup message and waits for operator override(FIG. 4, at 538). If there are no tilts pending, the low level driver 40manager will start comparing the generated driver/hardware list with thelist of the previously loaded drivers keep in the NV storage set (seeFIG. 4), starting at 603.

The comparison process in FIG. 4 is done to find what hardware, if any,has changed since the last power down. The low level driver managerstarts at the beginning of the new list at 604 created as attachedhardware devices were processed. If the entry was deemed to be invalidor an “IGNORE” error message issued, the low level driver manager willsend a message for that reported hardware type to the game systemmaintenance log informing it what action was taken. If the hardwareentry had a valid driver loaded, the old list in NV storage is scannedfor any matching entries at 604 through 630. The serial number of thehardware must be the same between the new and old list of entries, or—ifit is a hardware device that doesn't have a serial number—the hardwaretype, revision and lack of serial number must match that information inNV storage at 628. If there is a match at 628, but the revision of thehardware or driver changed 636, the low level manager will report thechange to the game system maintenance log and remove the old entry fromthe old list. (FIG. 4, at 606-636). If the match was exact, no report ismade, but the entry is removed from the old list at 636. If there is nomatch, a report is made to the game system maintenance log that there isa new hardware device and the report will include all of the informationin the attached hardware entry. After all the entries in the new listare finished being process, all the entries remaining in the old listare reported as removed to the game system maintenance log. The laststep shown at 610 is to move the new list to the old list in the NVstorage set, at which point (612), the hardware comparison and updatingof the low level driver system is complete. For those hardware itemswhich do not have a serial number, information as to the hardware type,revision, and absence of a serial number are recorded in NV memory foruse later.

The resource manager control task 20 next loads the High Level DriverManager 50. In addition to the jurisdiction error table 550 that the lowlevel driver manager contains, the high level driver manager also hastwo extra tables. These are the “Repository” (FIG. 4 at 570) and the“Load” table 599. The Repository table 510 converts the repository nameto a known index (572) and, at 574, indicates whether the repositorytype is prioritized, general or unknown. An unknown repository typemeans the system has no knowledge of the repository name, in question.The Load table is a table of high level drivers, both software andhardware, that should be loaded on creation of a repository, indexed onjurisdiction and repository. (FIG. 4, at 599-601).

The Driver Pool associated with the high level driver manager (see FIGS.1, 50, 60, 80, 90 and 100) also has a “Hardware” index and table (FIG.4, at 596). The high level driver pool hardware index is based uponjurisdiction, hardware type, high level driver name, and low levelhardware revision as shown at 597 and 598. This index will point into atable of high level driver revisions that match the hardware revisionlevel. The high level hardware driver table 596 contains an alternatesoftware driver in 598 that is used if a matching low level hardwaredriver is unavailable. The alternate software driver could link to otherhardware drivers to provide a software alternative to call otherhardware, software to simulate the missing hardware, or it could serve ashell function and have the repository control task 20 continue andsearch for the next driver. If there is no entry in the index for theexisting hardware revision, or the entry points to an “IGNORE,”“WARNING,” “TILT” or “FATAL” entry in the table then there is nomatching high level driver for the low level driver hardware.

The high level driver pool 60 has a third index and table named“Priority” (FIG. 4, at 580). This table uses an index 582 built fromjurisdiction, repository and driver name. The priority index places allthe software and hardware drivers in hierarchical order for eachjurisdiction and repository, but only for Prioritized repositories.While the I/O communication driver 30 and low level driver manager 40are loading, the game software continues to load the rest of the gametasks. The high level driver manager 50, once loaded, waits for theserepository control tasks to request the resource manager 20 to createtheir repositories starting at 700. (See FIG. 5.) When a creationrequest for a repository comes in, at 702, the high level driver managerfirst looks to determine what type of repository it is, using the“Repository” table at 704. If at 706 the repository was not found in thetable, the high level driver manager marks it unknown at 718. If, at 708the repository is known to the system, the high level driver managerkeeps track of the repositories' type and index as shown in 708 andsucceeding steps. For general and prioritized repositories, the highlevel driver manager will create a repository list that will contain allthe drivers loaded. The list will also provide information on therevision level of the driver, whether it is a hardware or softwaredriver and the priority of the driver. For hardware drivers, thehardware type, the hardware revision and the alternative driver entryfrom the hardware table will also be loaded into the repository list.For an unknown type, the high level driver manager creates a blankrepository list and informs the repository controlling task that therepository is of a type unknown at 718, and at 720 the high level drivermanager has completed the repository creation. The repository task thenhas the burden of requesting drivers to be loaded; and if they need tobe prioritized, the repository task will also have to do theprioritization. The steps of establishing the priority of the variousdrivers is shown in FIG. 5, from 752 through 780. If the repository typeis known, the high level driver manager then uses the Load table withthe current jurisdiction and repository index set to the beginning, tostart adding drivers.

The high level driver manager has received the current driver name andat 716 (FIG. 5) queries in the high level hardware driver pooljurisdiction index 597 to see if its allowed at 728. If the driver isnot found in the hardware table at 726-754, the repository control taskis informed and the high level driver manager looks in the jurisdictionerror table 560 for the not found error to see if the action it shouldtake is to:

-   -   (1) “IGNORE” it;    -   (2) post a “WARNING;”    -   (3) post a “TILT” message and allow the operator to override; or    -   (4) post a “FATAL” message and lockup in a manner similar to        that previously described for the low level driver manager.        All tilt message posts will pend until the resource manager is        informed that all repositories are created. Other action types        are executed as they occur.

If the found driver in the high level driver pool is allowed (at 726)for the jurisdiction, and it is a hardware driver, the high level drivermanager scans the loaded low level drivers for hardware of the same typeat 728. If the high level hardware driver matches a low level driverhardware type at 730, then at 732, the high level driver manager checksthe revision of the hardware and high level driver name to see if thereis a matching high level driver revision in the hardware index. If thereis no matching low level driver loaded, the alternate software driver isloaded at 740. If no high level driver is found at 716, the high leveldriver manager checks the Error table 560 for error type and informs therepository control task of the mismatched hardware revisions at 746. Ifthe hardware table indexes 597 (FIG. 4) didn't point to an action type,the high level driver manager checks the jurisdiction error table 560 tosee what action should be taken. If there have been no problems up tothis point, the actual level driver is loaded at 730. If the driverbeing loaded is a hardware driver, the high level driver manager willpass the driver the information to allow the high level driver theinteractions shown between the low level drivers 42, 44, 46 and 48 withhigh level drivers, such as 42-52, 44-54) to make a connection to thecorresponding low level driver. After being loaded, the driver will runinternal compatibility checks as needed. An example of a possible checkis one piece of hardware needing another piece of hardware to be presentfor the first to work properly. If during the checking process, anyitems the first driver requires are missing or incompatible, the driverwill return either a missing hardware error, or a revision error codefor incompatibility problems, to the high level driver manager and exit.If the high level driver manager will execute the same action for thesecond piece of hardware, as in the revision error case. The drivererror reports could be delayed until all repositories are created andloaded. After loading a hardware driver, the high level driver managerwould continue to scan the low level drivers for hardware of the sametype. If the high level driver manager finds another low level driver ofthe same hardware type, it will go through the load process describedabove and load another high level driver to communicate with theadditional low level driver. The high level driver manager continuesthis scanning process until it has scanned all of the low level drivers.Low level drivers 70 can only know the existence of and communicate withthe I/O communication driver 130 and the low level driver manager 40(FIG. 1.), the low level drivers are programmed so as not to be aware ofother drivers or tasks running. High level drivers can be programmed toknow if other high and low level drivers are loaded. No driver shouldknow about the internal workings of any other driver. If drivers haveknowledge of internal functions of other drivers, the software is hardto maintain or update. High level drivers can communicate with loadedlow level drivers, the high level driver manager, other loaded highlevel drivers in all the repositories and system level tasks in the caseof software drivers, as shown in FIG. 1.

This visibility of other drivers can be used for drivers in prioritizedrepositories to change the order of execution in a prioritizedrepository as needed, and in the case of general and unknownrepositories, actually call other drivers as needed after theythemselves were called by the repository control task or other drivers.As each default driver load is completed for a repository, and therehave been no errors that could cause the system to halt, the high leveldriver manager will put the drivers in order if the repository is of thetype prioritized. (See FIG. 5.)

In the repository list the high level driver manager made as it loadedeach driver in the prioritized repository, there is a field for priority(reference numbers 580-584, FIG. 4.). This priority field at 584 issimply a number from one to the maximum number of drivers in anyrepository. The driver pool for the high level driver manager has atable and index, named “Priority”, built of jurisdiction, Prioritizedrepository index (based on the repository name) and the driver name.This index points to entries numbered from one to the maximum number ofdrivers possible. The high level driver manager starting at 750-762(FIG. 5) uses this index to scan the repository list and fills in thepriority field with the number from the index. If during any of thescans, the index search is missing an entry at 764, 770, for thatjurisdiction/repository/driver combination, the high level manager looksin the jurisdiction error table at 770 for the action on this type oferror. If there are no serious errors, (778) as defined by thejurisdiction error table, the high level driver manager then does a sorton the repository list based on the priority field at 758. If there areseveral of the same hardware drivers loaded, because of severaloccurrences of the same type of hardware, as part of the gaming device,the priority field in the list would be the same and the high leveldriver manager would request these drivers to order themselves. Themultiple high level hardware drivers do this based on internalconfiguration data received from the hardware. For example, if driversfor two hoppers are loaded, the driver for the coin hopper having thehigher denomination coins would be ordered in the list before driver forthe coin hopper for coins having the lower denomination. Now that therepository list is ordered, or the repository is not a “priority” type,the high level driver manager informs the repository control task thatthe repository creation is complete. The repository control task thenreads the repository list, and can request drivers to be loaded,unloaded, or the order changed. Usually, the repository control taskwill not need to make any changes. Any repository task requested changesare treated just like loading a driver during the default load (SeeFIGS. 4 and 5). If there are any errors, the same handling would occur.Once the repository control task has made all the necessary changes, andthere have been no errors that would halt the system, the repositorycontrol task informs the high level driver manager that the repositoryis complete with respect to the repository control task. At this point,any alternate software drivers loaded in the repository will run checksto see if the missing hardware driver was needed for proper operation ofthe repository. If the hardware is not needed, the alternate drivercould need to re-prioritize the repository or do nothing. If thehardware was needed, the alternate driver will inform the high leveldriver manager. The high level driver manager now compares the currentrepository driver list to the previous driver list stored in the NVstorage set, but only if the resource manager and game software revisionlevels are the same as previously recorded (i.e., prior to the lastpower down) in the NV storage set. This process is similar to what thelow level driver manager process did FIG. 4. After any new, missing, orchanged high level drivers have been reported, the high level drivermanager has completed the repository list creation and the newrepository list is stored in the NV storage set in place of the oldrepository list. After all the repositories have been built, the gamesoftware informs the resource manager control task that there are nomore repositories pending and the resource manager is now completelyloaded and operational.

While powered up and operational, new hardware may be added, or currenthardware may be removed without affecting the gaming software. Thehardware abstraction specified in NuGame's Patent Application Ser. No.60/094,068, for I/O Interface and Device Abstraction Patent, filed 24Jul., 1998, allows hardware to be hot-swapped (removed or added withoutturning power off). As hardware is removed or added, the IOCB 120 sendsa removal or added message to the I/O Communication driver 30. The lowlevel driver manager 40 is notified and it first checks the jurisdictionerror table to see if the game is allowed to hot-swap hardware. Theaction specified is taken and, if it is “IGNORE” or “WARNING”, the lowlevel driver manager 40 will process the notification. For anotification that hardware has been added, the low level driver will gothrough the driver loaded process as described above and flowchart inFIG. 4.

If there are no errors of a type “TILT” or “FATAL” and a driver wasloaded (FIG. 4 at 520, 532, 530), the low level driver manager theninforms the high level driver manager of the newly loaded hardware typeand hardware revision. The high level driver manager then scans thehardware index for an index that matches the jurisdiction, hardwaretype, and low level hardware revision. The index that matches thosethree parts points to the high level driver to be loaded. If no highlevel driver is found, the high level driver manager looks in thejurisdiction error table at the “hot-swap” error index of the errortable at 560 through 564 for the error action to take. If the high leveldriver entry was found in the hardware table, the high level managerthen uses the alternate driver name to scan all of the repository lists(shown generally in FIG. 5, from 704 through 740). Since this is newhardware, any of the repositories that would have needed it loaded wouldhave had to load the alternate driver on power up. For every match ofthe alternative driver the high level driver manager finds in therepository lists, the actual hardware driver will be loaded. Once allthe repositories have been scanned, the high level driver managerinforms the repository control tasks that had changes made in theirrepository lists that they need to rescan their list. The high leveldriver manager logs the “new hardware added” message to the game systemlog. The high level driver manager then saves all the changed repositorylists to the NV storage set.

As shown in FIG. 6, hardware removal works a little differently than theprevious example and the power up case. (See FIG. 6). The message fromthe IOCB 120 that a hardware device has been removed is delivered to theI/O communication driver 30. The I/O communication driver 30 sends theremoval notification to the low level driver manager 40. The low leveldriver manager 40 removes the low level driver that matches the hardwaretype and revision and then sends the removal notification to the highlevel driver manager 50 (FIG. 1). Using the hardware type and revisionin the message, the high level managers at 802 (FIG. 6) scans all therepository lists for matching hardware types and revisions. For eachmatch, the repository list will have listed the alternate softwaredriver for that high level hardware driver. The hardware driver isunloaded at 828 and the alternate driver is loaded at 834. If hardwarewas required for this jurisdiction at 836, the alternate driver willinform the high level driver manager. Looking in the jurisdiction errortable 840, the high level manager will see what action to take for arequired hardware device being removed. All “TILT” actions will penduntil all the repository lists have been scanned. If the action is not a“FATAL” tilt lockup, (such as at 848) the high level driver managercontinues to scan all the repository lists. After all the lists havebeen scanned the alternate drivers that were loaded are informed, andthey in turn run their checks. The alternate driver may inform the highlevel driver manager that the hardware is required, in which case thehigh level driver manager at 850 sends a missing hardware message to thegame system, or the software driver may re-prioritize the lists. Oncethe software drivers report everything is okay at 836, the high leveldriver manager informs the repository control tasks to re-scan theirrepository lists. The high level driver manager reports the new hardwareto the game system log and then saves the changed repository lists tothe NV storage set processing is complete, and at 824 the resourcemanager is operational again.

Some examples of the gaming device's resource repository function types,but not limited to these, are: pay, collect, multi-player and gameinterface (such as buttons, reels, bonus hoppers, lights, towers,meters, jackpot bells, etc.). To see how the repository control taskuses the repository drivers, use of the pay and game interfacerepositories will be given as examples. The first two examples are ofthe pay prioritized repository (FIG. 7), and the last example is of thegame interface general repository (FIG. 8).

The repository control tasks call the drivers in their repositories toprocess or control objects in the repository. The repository controltasks for prioritized repositories need very little extra intelligence,since the high level driver manager will load the needed drivers for thecontrol task to handle their duties. The drivers loaded by the highlevel manager are the default drivers for the whole game. This softwareis designed as a multi-game platform, meaning the player chooses whichgame to play. If the chosen game has an unusual feature or way to usethe hardware that differs from default, it will have to ask for otherdrivers to be loaded or unloaded. The repository control tasks will needextra intelligence when specialty games are loaded that requirenon-standard usage of the hardware. Non-standard usage would be usageother than the default hardware usage by most games. General and unknownrepository control tasks must have intelligence built into them torequest needed drivers if they have not been loaded. General and unknownrepository control tasks must know which drivers to call in order tohandle different operations on the different repository objects at 902.In all cases, at 908, the repository control task calls a driver,passing it an object message for the driver to operate on. When calledby a repository control task, a driver could:

-   -   (1) do nothing and return the object unchanged with a control        message (at 910, 914, 918), to the control task, to call the        next driver;    -   (2) partially process the message, call another driver with the        changed message, return the changed message with a control        message to call the next driver, return the changed message with        a control message to call a specified driver (910, 914, 916);    -   (3) process the whole message, returning a processed object        message with control message that the processing is complete at        913.

Given these factors the pay repository is a prioritized repository. Ithas the following drivers loaded in order:

(1) lockup;

(2) credit;

(3) hopper: and

(4) call attendant.

For example, assume that a game is won, resulting in the payment of 80credits, the following pay routine will try to distribute the payaccording to the actions of the high level drivers it calls. The payrepository control task starts with lockup, the first driver entry inthe prioritized repository list. The pay repository control task sendslockup a pay message object having the value of 80 credits in it. Lockuplooks at the value, of 80 credits and converts it to dollars to compareit against the lockup limit for the current jurisdiction. If 80 creditsis less than the lockup limit, the lockup software driver returns themessage unchanged to the pay repository task with 80 credits still in itand a control message for the pay repository task to go to the nextpriority driver. The pay task sends a pay message with 80 credits to thecredit software driver. The credit software driver checks to see if thecurrent number of credits plus the 80 credits in the pay message objectwould put it over the limit for the credit meter. If it is okay, thecredit driver adds 80 credits to the paid meter and the credit meter.The credit driver then returns a pay (i.e., no more credits to process)message object with zero credits left and a control message for paycomplete.

As another example, assume a game win of 1400 credits (See FIG. 7). Thepay routine 930 sends a pay message 932 object to the lockup driver witha value of 1400 credits. The lockup driver logic decides to hand pay the1400 credits, but have part of it paid from the hopper, so the playerhas some money to play the neighboring game while waiting for theattendant to hand pay the remainder (936). The lockup driver at 934calls the hopper driver at 938, as if it were the pay control task, witha pay message object of 50 credits 936. The hopper driver pays out the50 credits at 940 from the hopper hardware, updating the paid meter, andreturns a pay message at 942 with zero credits left and a controlmessage for pay complete to the lockup driver at 944. The lockup driverat 944 returns a pay message object of 1350 credits at 946, and acontrol message for the pay repository control task to go to the callattendant driver next. The pay control task 958 sends a pay messageobject 946 of 1350 credits to the call attendant driver 948. The callattendant driver eventually hand pays the 1350 credits, updating thepaid meter at 950 and returns a pay message with zero credits left at952 and a control message for pay complete at 958. Notice that the callto the hopper at 938 was from the lockup driver, so when the controlmessage from the hopper saying pay complete was passed back, it was tothe lockup driver at 944 and not the pay repository control task.Otherwise, the pay control task would have had to reconcile the factthat credits are left while a driver says the pay function is complete.All repository control tasks should have logic to catch this incompletemessage processing. If the control task finds that the message object isstill not completely processed, while the driver informs the controltask that the task is complete, the repository control task should senda request for jurisdiction lookup to the high level driver manager forwhether the tilt in the current jurisdiction is a warning tilt thatallows operator override or a fatal tilt that locks up the game. If thetilt action returned from the high level driver manager's lookup in thejurisdiction error table is not either of those two error actions, therepository control task will default to a fatal tilt lockup.

The game interface repository has many different types of objects. Thefollowing example will deal with only two drivers: (1) the buttons and(2) reels drivers. Whenever a game is loaded for play, whether selectedby the player, or loaded as the system configured game, the first thingthe game does is to make sure that the hardware is available for thegame to be playable. In our example, a reel game is loaded.

The gaming software reads the game interface repository list to makesure that the reels driver for the reel hardware is there and deckbuttons are available by checking the buttons driver. The game software,using the game interface repository control task, then queries theconfiguration of the reels and buttons drivers. If the reelconfiguration does not match the needs of the game specified by thegaming software, such as number of reels number of stops per reel, andloaded reel strip symbols, the gaming software will have to declare anerror. This level of error will not be decided by the high level drivermanager's jurisdiction error table, but by the game software itself. Thegame software also asks for the buttons configuration. If the deckbuttons installed do not have the right layout, number, or labels, tomatch the game needs, the game software will have to declare an error.If there are no errors, the game software then sends the reels driver aconfiguration message with the default spin direction, stop order, andstarting position. These defaults are attributes of the reels driverobject type. Spin direction would be up or down. Stop order would bewhich reels stop before other reels can stop, e.g. reel one, then reeltwo and then reel three, or all stop as soon as possible. The startingpositions are the symbol positions that should be showing on each reelas recorded for the previous game in NV storage. The reel driver spinsthe reels to the starting positions. As each reel stops, the reel driversends a reel stop message, indicating reel number and stop position, tothe game interface repository control task. These messages allows thegame software to verify that the stop positions and stop order are setcorrectly.

The configuration of the game buttons varies. The game software sends aconfiguration message to the buttons driver. The buttons driver that hasa mask reserving buttons for game use only, a mask for buttons that canbe used by the state machine software, a mask for buttons that cannot beused at all, and a mask for which buttons the game will accept inputsfrom currently. The input mask changes as the game proceeds from stateto state, e.g. game over, to bet, to game play, to pay state and back togame over. The buttons driver sends a message copy of these masks to thelamps driver, so it will know which button lamps can be turned on, whichbutton lamps must always be off, and which lamps to turn on currently.Unless the game needs to use special handling of the lamps, such asflashing, the lamps driver is not accessed directly by the game; thegame will depend on the buttons driver to link to and control the lampsdriver. As button presses are sent up by the hardware, the buttonsdriver will mask out the buttons that are not wanted by the games andonly send button messages to the game interface control task for buttonsin the input mask (see FIG. 8, 1000-1010). Now that the game has thedriver configurations set, the example will start with the game state at“GAME OVER”, no rebet amount, and the game has more than maximum betcredits available. For these settings, the buttons input mask would beset to accept button input from buttons marked “bet one” and “betmaximum”.

The machine at this state would have a buttons mask set for allowing thecollect and change button, but these buttons would be routed to themachine and not the game. (See FIG. 8.) For a given state only certainoperations, inputs, or outputs can be performed (i.e., the buttons aremedal). The machine progresses through different states in a fixedfashion. As the player presses the “bet one”, or “bet maximum” buttonsat 1020, the game state changes from “game over” to “bet” at 1030. Thegame sends a new button input mask at 1032 to the buttons driver at1034. The state machine also sends a new button mask to the buttonsdriver turning off all inputs to the state machine. The new input maskfrom the game will turn the spin button on, if “bet maximum” was notpressed. If “bet maximum” was pressed, all button inputs to the gamefrom the buttons driver will be turned off, and the game will change to“game play” state. In the case where “bet one,” “bet maximum”, and“spin” buttons are lit while the gaming machine is still in the betstate, the game will change to “game play” if the spin button or “betmaximum” is pressed or the “bet one” button is pressed enough times toreach maximum bet. Now that the game is in “game play” at 1068, thebutton inputs are masked off and sent to the buttons driver, the gamedetermines the random stop positions for the reels and send the “reelstop” messages with those positions to the reels driver. The game thenstarts playing the reel spin sound effects. As each “reel stopped”message comes back from the reels driver to the game, the game comparesthe stopped position with the position sent and, if they match, playsthe stop sound effect. If the reel was not the last reel to be stopped,the game starts playing the reel spin sound effects again. If thestopped positions do not match, the game will declare a tilt, and thereels driver will inform any reels that are still spinning to continueto spin indefinitely. In the case there is no error, the game willevaluate the stop positions. If the stop positions a winner, the gamegoes to the pay state, as in the above examples; otherwise, the gamegoes directly to game over. After the game is over, if there are anycredits left on the credit meter, the bet one button is set on in thebuttons input mask. If there are enough credits available for what wasbet in the previous game, and the game allows rebet, the spin button inthe buttons input mask is set on. If there are enough credits availablefor maximum bet, the bet maximum button is set on in the buttons inputmask. Now the game sends the new input mask to the button driver. Thatcompletes a game play cycle. As new devices are added to the gamingmachine, the resource manager is usually the only software in the systemthat needs to be updated other than the added new drivers. When newdrivers are added, the driver manager and drive pool indexes and tablesmust be updated to contain the new driver for the resource manager tounderstand it. (See FIG. 4 for a diagram of the tables and indexes.) Ifa new driver is loaded that the resource manager can't find addressedconsistently in all the tables and indexes, the driver manager will lookup the error action called for in the current jurisdiction in thejurisdiction error table. If none of the indexes and tables for thedriver managers and pools are updated to contain the new driver, thedriver managers will not be able to use the driver. If the repositorycontrol task requests the new driver be loaded, there will be an errorbecause the new driver isn't in the table and indexes. The changes tothe resource manager, when a driver is changed, are in effect, databasechanges. Any driver change can be considered to be one of three databasetransactions: (1) add; (2) change; or (3) delete. These transactions areconducted on the tables and indexes of the driver managers and driverpools. Overall, this allows hardware devices that are properly throughthe I/O interface to be added at will with little to no changes requiredin the game or resource manager software. When a new driver isdeveloped, the additions for the driver manager and driver pool tablesand indexes are bundled with the driver, in what is referred to an addpackage. The package has a header informing the resource manager controltask that the package must be added, and whether it is a high leveldriver or a low level driver. The add package could have one or both ofa new driver in it and/or new table and index entries. In all cases anadd package would have the driver name, revision, and appliedjurisdiction in it.

For an existing driver that needs to be removed, the drive name,revision and jurisdiction is bundled with the table and index entriesthat are to be deleted. The bundle would also have an entry for whetherthe driver was to be removed also and there would not necessarily be anytable or index entries. This a delete package. The package has a headerinforming the resource manager control task whether to remove instancesof the driver, as identified by revision and jurisdiction, from the highor low level pools, and if there are table and index entries, to removethem also. Any package will only affect the high level drivers or thelow level drivers, never both.

A change package is a bundle containing a delete package and an addpackage. If all the table and index entries were okay for a driver, butthe driver has a but, the change package would contain a delete of thedriver from the driver pool, and an add of the new driver code to thepool. A change could also consist of only deleting old table and indexentries, followed by adding new entries. For a more comprehensivechange, both the driver code and table and index entries would bedeleted, and then a new driver and entries added. If the storage mediais write enabled, the package can be downloaded to the game softwarefrom a central computer or network server using a communications link.Based on what the current jurisdiction allows, the game software willperform some authentication to insure that the package is acceptable touse and send it to the resource manager control task. The resourcemanager control task will route the package to the correct high or lowlevel driver manager which will apply the package. In the case that thestorage media is read-only, a new copy of the game software would beinserted with the correct drivers, tables, and indexes during power downof the gaming machine and no packages are involved or allowed. If theresource manager software must be updated, a copy of the new resourcemanager can be downloaded if the storage media is write enabled. Wherethe new driver and resource manager is contained in a read-only copy ofthe updated storage media (such as CD-ROM, ROM PCMCIA, EPROM, etc.) thisstorage medium must be placed in the game. In the case of read-onlymedia, the game would be powered down to make the change, and on powerup, would use the new resource manager. If the new resource manager canbe downloaded directly to the game, the currently executing resourcemanager is informed that there is a new resource manager. The oldresource manager waits until the game state is between game play, andmomentarily blocks game play while it loads the new resource manager inits' place. The new resource manager informs all the repository controltasks that their repositories need to be recreated. The new resourcemanager would then proceed as if the game had just powered up. Once thenew resource manager has all the drivers loaded and the game softwareinforms the resource manager that no more repositories are to becreated, the game software also allows game play to continue.
